IMPROVEMENT IN BOTTLE-STOPPERS.

Specification forming part of Letters Patent No. 182,357, dated September 19, 1876; application filed May 5, 1876.

To all whom it may concern:

Be it known that I, JASON CLARK, of Allegheny city, in 'the county of Allegheny and State of Pennsylvania, have invented a new -and useful Improvement of Bottle-Stoppers;

My invention relates to the means for and manner of securing stoppers in and to botties; and has for its object to simplify, cheapen,

and render effective that class of bottle-stop-V pers wherein the stopper is hinged on one side, and secured at `the other side by a catch.

I will now proceed to describe my invention, so that others skilled in the art to which it appertains may applythe'same.

A indicates the neck of a bottle, and B a stopper, of any suitable material, preferably rubber. This stopper B is fastened to a strip or plate, C, of stiff metal by means of the rivet b, the head of which, or a metal washer, supports the under surface of said stopper.

In order to insure the stopper engaging evenly with the lip and entering fairly the neck of the bottle, I curve or bend the metal plate C substantially as shown. If desired, this plate may be of elastic material, such as spring-steel; but, in general, where the stopper is of rubber, it is notnecessarily so, but is preferably of metal which will retain the bend or curve given to it, so that by the stroke of a hammer or like device the convexity of C may be increased to take up any slack oceasioned by Wearl or compression of the stopper'.

Both ends of plate C are turned over, or like means taken, to form a hinge with the bail, as at c, and alug, c', to engage with the opposite stirrup of the bail.

D represents the bail, which is readily formed metal plate C having been struck up to the' desired curve, and provided with the loop and lug c c', or equivalent devices, in any suitable manner, a piece of wire, of sufficient length to form bail D, is passed through one loop ot' the plate, then bent to form a stirrup, and twisted upon itself for about one-third of its length. rIhe oppositeend of the wire is also bent to form a loop or stirrup, and Wound upon itself toward the middle, making, when complete, the bail shown in Fig. 3. The single thickness of wire (at the middle) is applied ,to the neck of the bottle, and the free ends are then brought together and twisted, after which the stirrups may be turned up against the neck ofthe bottle, as shown in Figs.'l and 3.

The advantages arising from my improved construction of stopper and attachment are,

the cheapness of manufacture, the facility with which they may be applied, and the readiness with which adjustments can be made to compensate for Wear or compression ofthe stopper.

Havingthus described my invention, what I claim, and desire to secure by Letters'Patent, is-

l. In combination with a bottle-stopper of the class specified, and the bail for securing the same, the curved or convex spring-plate, to which the stopper is` secured, substantially as and for the purpose specified. Y

2. In combination with a bottle-stopper, the

curved spring-plate C, having the loop andf lug c c and the double-looped wire, forming both pintle and catch, substantially as and for the purpose specified.

In testimony whereof I, the said JASGlV CLARK, have hereunto set my hand.
